Introduction

JJF 1071-2010 "Rules for the preparation of national metrological calibration specifications", JJF 1001-2011 "General measurement terms and Definition ", JJF 1059.1-2012" measurement uncertainty assessment and representation "together constitute the support of the calibration standard development Work of the basic series of norms. This specification is the first release. Battery internal resistance tester calibration specification

1 Scope

This specification applies to the principle of AC injection method of the battery internal resistance tester calibration, with the battery resistance test function Calibration of the corresponding items of the battery test system can also be performed with reference to this specification. This specification does not apply to the principle of DC discharge Calibration of battery internal resistance tester.

2 reference file

This specification refers to the following documents. Electrotechnical terminology - Primary batteries and accumulators GB/T 2900.41-2008 For dated references, only the dated edition applies to this specification; references that are not dated , The latest version (including all modifications) applies to this specification.

3 terms and units of measurement

The following terms and definitions apply to this specification. 3.1 battery internal resistance batteryinternalresistance Under the conditions of the battery voltage changes with the corresponding discharge current changes, also known as the apparent resistance.

4 Overview

Battery internal resistance tester is used to measure the battery resistance of the instrument, according to the purpose can be divided into special and general type, according to the original Can be divided into exchange injection method, DC discharge method. Commonly used battery injection resistance method based on the principle of manufacturing battery resistance test Instrument, generally by the AC constant current source, lock-in amplification unit, DC voltage measurement unit, comparison and alarm circuit and control And instructions (display) and other components, it is applied to the measured object to a certain frequency (usually 1kHz) of the AC current Signal, the use of lock-in amplification technology to measure the measured internal resistance of the battery voltage drop, the internal impedance value. Block diagram of the principle As shown in Figure 1. Figure 1 block diagram of the battery resistance tester
